The Chief of Staff of the Armed Forces of the Philippines (CSAFP) is the highest-ranking military officer (except for the President of the Philippines, who holds the position of Commander-in-Chief equivalent to a five-star general) and the head of the Armed Forces of the Philippines (AFP), including all service branches (Army, Air Force, Navy–Marine Corps, Coast Guard—in Wartime Attached Service) under its command. The position is usually held by a four-star rank of General or Admiral. Its direct equivalent in the US Armed Forces is the Chairman of the Joint Chiefs of Staff. Unlike its US counterpart, which is merely supervisory, the Chief of Staff has complete operational control and is responsible for the overall operations of the AFP. The holder of this position is appointed by, as well as directly reports to the President of the Philippines under the Article VII, Section 18 of the 1987 Constitution. He executes the President's commands, tactics, operations, plannings, and strategies, as well as serves as the Immediate Adviser to the Secretary of National Defense. He also prescribes directions to all commands (including the Commanding General of the Philippine Army, the Commanding General of the Philippine Air Force, the Flag Officer-in-Command of the Philippine Navy, the Commanders of the AFP Unified Commands, and the AFP Board of Generals). The Armed Forces of the Philippines were created as a result of the Commonwealth Act No. 1, also known as the National Defense Act of 1935. However, the origin of the organization can be traced back to the establishment of the Philippine Constabulary, armed Filipino forces organized in 1901 by the United States to combat the Philippine Revolutionary Army then led by General Emilio Aguinaldo. History The position of the Chief of Staff has been traced from the Commanding General of the Philippine Army, when the Philippine Commonwealth Army (now the Philippine Army) was established as the main army of the Commonwealth of the Philippines. After the defeat of the First Philippine Republic during the Philippine–American War, the United States dissolved the army and relied on its armed forces together with some Filipino troops under the Philippine Constabulary. However, the National Defense Act of 1935 led to take on responsibilities on national defense and pave way for the creation of three major commands (Army, Air Force, Navy). Since the 1960s, the rosters of the Chiefs of Staff is arranged accordingly. On June 19, 2020, under
